HomeBackend DevelopmentPHP TutorialPHP把数字转成人民币大写的函数分享_PHP

做财务的人遇到过这么一个问题,比如13,126.8元,在发票或者其他记账业务中,一般要使用大写进行拼读成“壹万叁仟壹佰贰拾陆元捌角整”。

这不,也贴上我原来在做学车网的一个php函数,供大家参考吧。
复制代码 代码如下:
/**
 * 人民币小写转大写
 *
 * @param string $number 数值
 * @param string $int_unit 币种单位,默认"元",有的需求可能为"圆"
 * @param bool $is_round 是否对小数进行四舍五入
 * @param bool $is_extra_zero 是否对整数部分以0结尾,小数存在的数字附加0,比如1960.30
 * @return string
 */
function rmb_format($money = 0, $int_unit = '元', $is_round = true, $is_extra_zero = false) {
    // 将数字切分成两段
    $parts = explode ( '.', $money, 2 );
    $int = isset ( $parts [0] ) ? strval ( $parts [0] ) : '0';
    $dec = isset ( $parts [1] ) ? strval ( $parts [1] ) : '';
 
    // 如果小数点后多于2位,不四舍五入就直接截,否则就处理
    $dec_len = strlen ( $dec );
    if (isset ( $parts [1] ) && $dec_len > 2) {
        $dec = $is_round ? substr ( strrchr ( strval ( round ( floatval ( "0." . $dec ), 2 ) ), '.' ), 1 ) : substr ( $parts [1], 0, 2 );
    }
 
    // 当number为0.001时,小数点后的金额为0元
    if (empty ( $int ) && empty ( $dec )) {
        return '零';
    }
 
    // 定义
    $chs = array ('0', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖' );
    $uni = array ('', '拾', '佰', '仟' );
    $dec_uni = array ('角', '分' );
    $exp = array ('', '万' );
    $res = '';
 
    // 整数部分从右向左找
    for($i = strlen ( $int ) - 1, $k = 0; $i >= 0; $k ++) {
        $str = '';
        // 按照中文读写习惯,每4个字为一段进行转化,i一直在减
        for($j = 0; $j = 0; $j ++, $i --) {
            $u = $int {$i} > 0 ? $uni [$j] : ''; // 非0的数字后面添加单位
            $str = $chs [$int {$i}] . $u . $str;
        }
        $str = rtrim ( $str, '0' ); // 去掉末尾的0
        $str = preg_replace ( "/0+/", "零", $str ); // 替换多个连续的0
        if (! isset ( $exp [$k] )) {
            $exp [$k] = $exp [$k - 2] . '亿'; // 构建单位
        }
        $u2 = $str != '' ? $exp [$k] : '';
        $res = $str . $u2 . $res;
    }
 
    // 如果小数部分处理完之后是00,需要处理下
    $dec = rtrim ( $dec, '0' );
    var_dump ( $dec );
    // 小数部分从左向右找
    if (! empty ( $dec )) {
        $res .= $int_unit;
 
        // 是否要在整数部分以0结尾的数字后附加0,有的系统有这要求
        if ($is_extra_zero) {
            if (substr ( $int, - 1 ) === '0') {
                $res .= '零';
            }
        }
 
        for($i = 0, $cnt = strlen ( $dec ); $i             $u = $dec {$i} > 0 ? $dec_uni [$i] : ''; // 非0的数字后面添加单位
            $res .= $chs [$dec {$i}] . $u;
            if ($cnt == 1)
                $res .= '整';
        }
 
        $res = rtrim ( $res, '0' ); // 去掉末尾的0
        $res = preg_replace ( "/0+/", "零", $res ); // 替换多个连续的0
    } else {
        $res .= $int_unit . '整';
    }
    return $res;
}

使用就很简单了

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
